How to get user(authenticated) information even when user is not logged in?

I want to show user information publicly from built-in users table in Laravel. More specifically, Anyone can see user information(name, email, username) without logged in. I've used these in blade file:

But it only works when user logged in otherwise shows errors. Even I've used ELOQUENT in controller and have passed $user object with by view. I'm attaching images so that you can understand my problem. This is my PagesController file

And this is my welcome.blade.php file
